Plug connector assembly

Abstract

A plug connector assembly includes a first plug connector part arranged on a printed circuit board (PCB) and a second plug connector part. Stamped/bent parts are positioned next to respective sides of the first plug connector part and are fastened to the PCB. In one variation, each stamped/bent part forms a spring arm, and when the plug connector parts are connected, end sections of the spring arms engage in respective detent recesses (or notches) in a base body of the second plug connector part thereby fixing the plug connector parts together. In another variation, each stamped/bent part has a detent recess, and a base body of the second plug connector part has spring arms on respective sides of the base body which lock with the detent recesses in the stamped/bent parts when the plug connector parts are connected thereby fixing the plug connector parts together.

What is claimed is: 
     
       1. A plug connector assembly comprising:
 a printed circuit board; 
 a first plug connector part connected to the printed circuit board, the first plug connector part having first contact elements; 
 a second plug connector part having a base body and second contact elements held by the base body, the base body having first and second detent recesses on respective sides of the base body; 
 the first and second plug connector parts being connectable together, wherein the first and second contact elements are connected together when the first and second plug connector parts are connected together; 
 a first stamped/bent part and a second stamped/bent part, the first and second stamped/bent parts respectively positioned next to respective first and second sides of the first plug connector part and fastened to the printed circuit board, the first and second stamped/bent parts forming respective first and second spring arms that are each movable as one piece relative to the first and second sides of the first plug connector part, respectively, in parallel to the printed circuit board, wherein each of the first and second spring arms has an end section; and 
 wherein the first and second plug connector parts being connected together causes the first and second spring arms to move relative to the first and second sides of the first plug connector part, respectively, in parallel to the printed circuit board resulting in the end sections of the first and second spring arms respectively engaging in the first and second detent recesses of the base body thereby fixing the second plug connector part relative to the printed circuit board and thus also fixing the second plug connector part relative to the first plug connector part. 
 
     
     
       2. The plug connector assembly according to  claim 1  wherein:
 the end sections of the spring arms are detent hooks. 
 
     
     
       3. The plug connector assembly according to  claim 1  wherein:
 the stamped/bent parts are fastened to the printed circuit board by being soldered onto the surface of the printed circuit board. 
 
     
     
       4. The plug connector assembly according to  claim 1  wherein:
 the stamped/bent parts have a mirror-symmetrical design relative to one another. 
 
     
     
       5. The plug connector assembly according to  claim 1  wherein:
 the first plug connector part further includes a contact carrier, wherein the first contact elements are held by the contact carrier. 
 
     
     
       6. The plug connector assembly according to  claim 1  wherein:
 the first contact elements are connected to the printed circuit board. 
 
     
     
       7. The plug connector assembly according to  claim 1  wherein:
 the first plug connector part is connected to the printed circuit board irrespective of the first and second stamped/bent parts. 
 
     
     
       8. The plug connector assembly according to  claim 1  wherein:
 each of the first and second spring arms further has an actuating section, the actuating section of each spring arm being opposite to the end section of the spring arm; and 
 pressure being exerted on the actuating sections while the first and second plug connector parts are connected together causes the first and second spring arms to move relative to the first and second sides of the first plug connector part, respectively, in parallel to the printed circuit board resulting in the end sections of the first and second spring arms respectively disengaging from the first and second detent recesses of the base body thereby enabling the second plug connector part to be disconnected from the first plug connector part. 
 
     
     
       9. A plug connector assembly comprising:
 a printed circuit board; 
 a first plug connector part connected to the printed circuit board, the first plug connector part having first contact elements; 
 a second plug connector part having a base body and second contact elements held by the base body; 
 the first and second plug connector parts being connectable together, wherein the first and second contact elements are connected together when the first and second plug connector parts are connected together; 
 a first stamped/bent part and a second stamped/bent part, the first and second stamped/bent parts respectively positioned next to respective sides of the first plug connector part and fastened to the printed circuit board, the first and second stamped/bent parts having first and second detent recesses, respectively; 
 the base body having first and second spring arms on respective sides of the base body which respectively lock with the first and second detent recesses of the stamped/bent parts when the first and second plug connector parts are connected together thereby fixing the second plug connector part relative to the printed circuit board and thus also fixing the second plug connector part relative to the first plug connector part; and 
 wherein the first plug connector part is connected to the printed circuit board irrespective of the first and second stamped/bent parts. 
 
     
     
       10. The plug connector assembly according to  claim 9  wherein:
 the first and second spring arms have respective first and second bent sections which respectively lock with the first and second detent recesses of the stamped/bent parts. 
 
     
     
       11. The plug connector assembly according to  claim 9  wherein:
 the base body further includes a metallic connecting element connected between the first and second spring arms, the metallic connecting element and the first and second spring arms being integrally formed as one piece. 
 
     
     
       12. The plug connector assembly according to  claim 9  wherein:
 the stamped/bent parts are fastened to the printed circuit board by being soldered onto the printed circuit board. 
 
     
     
       13. The plug connector assembly according to  claim 9  wherein:
 the stamped/bent parts have a mirror-symmetrical design relative to one another. 
 
     
     
       14. The plug connector assembly according to  claim 9  wherein:
